Hi guys today was and is a hard training day.  I trained at king vs 1 pawn endings and now I lost from Lithuanian FM Sigitas Kalvaitis (2169) at a strange time control 5 min + 3 sec / move vs 45 min + 3 sec / move. I played very slow because i was surfing in other sites and i tried to play with the +3 sec but i missed an easy tactic .

Look at the cover picture and tell me which is the best move for white and why ???

The answer is Bb5 because threats mate with Qd4 so Bb5 +-

Stay tuned i will upload more position later from the endgames I trained
