  1. fulmarsky Go RBorja!
  2. MilsBees Buzzzzzz
  3. MilsBees Let's go Borja!
  4. fulmarsky (13...Ng4) black has double isolated c-pawns
  5. fulmarsky (13...Ng4) it's tense
  6. fulmarsky (15.Bg3) i think black may castle queenside, i'm not sure whether the BK should castle, or if it should castle
  7. fulmarsky (16.h3) knight supper
  8. fulmarsky (16...h5) oh could black play ...h5 hxg4 ...hxg4 opening the h-file and then swing the queen to h7
  9. fulmarsky (17.hxg4) oh is this risky to open the h-file
  10. fulmarsky (17...hxg4) is it... oh the tension...
  11. fulmarsky (17...hxg4) i guess maybe the WK has f2 as an escape square, and the bishop covers h2
  12. LemuelGullible I want to see c4
  13. LemuelGullible damn
  14. MilsBees Not a fan of Re3 from white
  15. fulmarsky gg!
