Day 221 / 144 to go

Today I continued with Soltis and came to a (famous?) game/position of Fischer:

I failed on the following line: Rxf7 Rc1 / Qf1 Rxf1  just like I failed on Rxf7 Rc1 / Qf1 h5 / Qxc1 Qxc1
In neither variation I properly identified that the rook on f7 can retreat to f1     8-(

Later on I actually did a Lommer:

Here I failed because I lacked to recognize that if white queens in the following variation, he does so with check!
Kb5 g4 / Kc4 g3 / Kxc3 g2 / h7 g1=Q / h8=Q Qa1 now Black get´s the queen on h8 - so I skipped this line as favourable for white - and therefore any chance for white to keep the draw.
But - white queens with check (and this makes the variation work and correct)!

In both cases I miserably failed due to the same louzy oversight: a check - and considering the relevant pieces and not just the threat of the opponent!  Hard work still ahead!  8-(
