1.d4Nf62.Nf3e63.e3d54.Bd3Bd65.Nbd2...I play the Colle with White as well, so I was familiar with White's ideas. I didn't really have a line prepared, but I knew as long as I played sensibly I wouldn't get run over in the opening.5....O-O6.e4dxe47.Nxe4Nxe48.Bxe4h68...Nd7for some reason I worried about Bxh7+. It doesn't seem dangerous though here.9.Bxh7+?Kxh710.Ng5+Kg811.Qh5Nf6Black's knight gets back in time.9.O-ONd710.c3Nf611.Bd3b612.Ne5Bb713.Qe2c514.dxc5?...Here my opponent makes a mistake but I didn't note it. How would I have to look at this position to catch this? I need to consider all CCT's as candidates and then note that after Bxe5 the natural Qxe5 leaves d3 hanging.14....bxc5??=A pity I didn't see the opportunity here. This spoils an otherwise fine game. However, we can learn from it.14...Bxe515.Qxe5Qxd316.cxb6axb617.Qc7Qd518.f3Qc5+15.f4Qc716.Nc4...Should I allow White to trade on d6? Why did I decide not to trade? Part of me thought that the bishop was too valuable to trade and that giving the two bishops to White was not good in this position.16....Be716...Rfd817.Nxd6Qxd618.Rd1During the game I thought it was important to keep the dark square bishop. I saw this position in my calculations but didn't realize it was good for Black.Ba6!17.Ne5...17.f5I did consider this pawn push although I didn't reallize think about how I would deal with it. Maybe I just considered that I would be able to take it and defend my bishop on e7.exf5=18.Rxf5Rad819.Bf4Qd720.Bc2=17....a5?!I had an idea of a minority attack here although it may have been a little impulsive.18.Be3Nd5This gave me the tempo I was looking for to get my knight to d5. This may not have been ideal, but it gave me some activity.19.Rad1?...Here White made a mistake. He may have noted the danger on the a7-g1 diagonal and noted that Bf2 was bad. He would have to give concession and waste a move bringing the bishop back, but it would have avoided the trouble he got into.19.Bf2?Nxf4-+19.Bd2Bf620.Qe4(20.Ng4Rad821.Nxf6+Nxf6=)g6My position is solid and my pieces are active.19....Nxe320.Qxe3c4!Initiating a combination to win the exchange.21.Bxc4Bc522.Rd4Bxd4I felt this was simplest.22...Rad8was considered as well. However, I don't think it's signficantly better or worse than what I played.23.Rfd1Bxd424.Rxd4Rxd425.cxd4-+23.Qxd4Rfd824.Qe3Ba6Simply trading down with a material advantage. Without this bishop, my opponent's queenside pawns become more vulnerable to attack.25.Bxa6Rxa626.Nf3Rad6Although a visually pleasing maneuver, it is not necessary and I could have done better with my move.26...a4makes a lot of sense, locking down the b2 pawn so I can attack it. In a way doubling on the file is not necessary yet as White cannot contest it. To find this, I should have thought of my general plan which was to attack White's queenside pawns and that allowing the b-pawn to advance would not so great.27.Nd4...In particular, my rooks like a little silly now with the knight blocking the position. Of course, I have a firm edge in any case, but since we're after improving, I need to note this.27....Qb628.Qf2...28.b3would have protected the pawn a little more.28....a4!Finally working to lock down the b-pawn.29.Re1a329...Rb8Maybe makes more sense to me, but I figured that the game move was winning as well and that I could just shift my target to the c-pawn.30.b3Rc831.Qe3Qc532.Qe5...32.b4Qc4I had something like this in mind here.(32...Qxc3?33.Qxc3Rxc334.Nb5Rcd335.Nxd6Rxd6and although Black should have a slight edge White is still kicking.)33.Qf2Qd3!32....Rd533.Qe3Qxc334.Qxc3Rxc335.Nf3Rc236.Ra1Rdc5Here my opponent resigned.0-1
