Since e5 fails on f5 1 Rf6 seems like a plan ...Bxf6 2.e5 with mate on h7 ...bxc3 2.e5 h6 3.Rxh6 with mate afterwards. ...h6 2.e5 with a similar mating plan on h7 ...Nxe4 2. Nxe4 Bxf6 3. Nxf6 ...Nxe4 2. Nxe4 and after any other move by black Nf6 with the attack on h7 looks like a winning attack
@hennns Qxf2 looks like a winning sacrifice Qxf2 2. Rxf2 Re1+ 3 Bf1 Rxf1+4 Kg2 Rxf2+ with mate or material advantage a few moves later. Qxf2 2. Kh1 Qxf1+ 3.Bxf1 Bb7+ 4. Bg2 Re1+
I dont see the faster in the second variant. In the first one Qxf2 2. Rxf2 Re1+ 3 Bf1 Rxf1+4 Kg2 Rxf2+ 5.Kh1 Bb7+ 6. Kg1 Rf6# 5.Kh3 Bf1+6. Kg4 h5+ followed by Be2 and Bf6 or 6 Kh4 Bf6+ and mating after Be2 or h5 and Be2
Bf2!! Bxf2 e7 Re3 a7. White is going to queen and subsequently win the game.
After Bf2 Black can't protect the bishop as the trade leaves whit with two passed pawns, making one of them a queen. Moving the Bishop away also fails to stop white from queening.
Essentially Bf2 solves the problem of Re3 by trading of one of Blacks pices (or deposesend it), thus giving Black only one piecs to stop two Pawns.
@un theBest Bf2 is the move I was looking for and noticing that Re3 blocks the bishop on f2 the main idea.
@timinator after e7 Re3 2.Bb4 black still controls e8 and a6 so white cannot promote. I think Kg8 wins after 2 Bb4, since Black can start running with its f and g paws and after 3 Kg6 Kf7 wins the pawn.
