where’s the problem?
1. Qe3+ and 2. Qg3+ and back again.. draw
My first thought is that black has perpetual check with 1.Qd6+ Ka5 2.Qb6+ Kb4
But wait, there’s more…
Push a pawn to a5, then one to b4.
White’s c pawn can try in vain to defend,
But black, taking back, brings the game to an end.

At first, I thought it was perpetual, but black has a mate on deeper thought:
1. …..Qd6
2. Ka5 Qb6
3. Kb4
And here, I thought the repeat back to Qd6 draws (“Defensive Chess Tactic” afterall), but I did look at the alternatives from here and found:
3. …..a5!
4. Ka3 b4
5. cb4 ab4#
Qd6 – Qb6 – a5 – b4 mates.

Andreas, your 1st move was good but note you meant Qd6+ followed by Qb6+ AND you missed a5+ and the deadly b4+ with mate to follow.
1.Qd6+ Ka5
2. Qb6+ Kb4
3. a5+ Ka3
4. b4+ axb4
5. Qxb4 mate
Interesting puzzle. Black can even win this. 😀
