I play longer time controls (usually 45|45, 30|30, not less than 15|10). I use an e-board (DGT Pegasus, Chessnut Air, Chessnut Evo, Chessup, etc) to play. If I somehow abandon the game, if I resign after a really obvious stupid move, or if it seems I am taking a long time it is likely the board is acting up. I don't ask for takebacks, I don't give takebacks. It is turned off in my settings.
